Prosperity Bancshares plans a stock-for-stock acquisition of Southwest Bancshares (SWBI). At closing, all SWBI common shares will be converted into the right to receive an aggregate of 4,062,520 shares of Prosperity common stock plus additional shares equal to 0.6469 times any SWBI shares issued from option or warrant exercises after the merger agreement date, with the total subject to reduction if SWBI’s equity capital falls below a defined $188,000,000 minimum (as adjusted).
Using an illustrative 6,278,720 SWBI shares outstanding and a Prosperity share price of $72.83, this equates to a headline value of $47.12 per SWBI share, before fractional share cash adjustments. On this basis, former SWBI holders are expected to own about 4.2% of Prosperity after closing, or about 4.0% when also giving effect to Prosperity’s separate acquisition of American Bank Holding Corporation. SWBI shareholders will vote on the merger and a possible meeting adjournment on January 22, 2026, and may instead exercise appraisal rights under Texas law. A pre-closing special dividend may be paid from SWBI equity capital exceeding the minimum, and the transaction is intended to qualify as a tax-free reorganization for most U.S. holders.
